S-94450A525 7/16"-20 ANSI/ASME 18.2.2 Hex Nuts

Key Features & Benefits at a Glance

• Superior corrosion resistance from 18-8 stainless steel material, ideal for harsh environments and extended service life
• Secure left-hand thread engagement prevents unintentional loosening in applications with counter-clockwise rotational forces
• Optimized thin profile design reduces weight and saves space in compact assemblies without compromising strength
• Precise Class 2B thread fit ensures smooth assembly and reliable performance with mating components
• External hex drive compatibility allows for standard tooling and efficient installation in various settings
• Fine thread spacing (UNF) provides improved vibration resistance and finer adjustment capabilities
• Full regulatory compliance with RoHS 3 and REACH standards, ensuring environmental and safety adherence

Professional Applications & Engineering Value

This 7/16"-20 UNF left hand thin hex nut is engineered to address critical challenges in industrial and mechanical systems. The 18-8 stainless steel construction delivers exceptional corrosion resistance, making it suitable for marine, chemical processing, and outdoor equipment where moisture and corrosive agents are present. Its left-hand thread direction is specifically designed for applications where reverse rotation is a concern, such as certain machinery shafts, mixing equipment, and rotating assemblies, preventing accidental disassembly. The thin hex nut profile is ideal for space-constrained applications, allowing for weight reduction and compact design without sacrificing the holding power required in high-vibration environments. Manufactured to ANSI/ASME 18.2.2 standards, this nut ensures dimensional consistency and reliable performance in demanding B2B and industrial fastener applications.

Specification Summary & Compliance
